High Density Commercial Wet Detention Pond Project
Pender County
Dear Mr. Sexton:
The Wilmington Regional Office received a complete Stormwater Management Permit Application for
Inter-Continental Hardwoods on May 2, 2011. Staff review of the plans and specifications has
determined that the project, as proposed, will comply with the Stormwater Regulations set forth in
Title 15A NCAC 2H.1000 and Session Law 2008-211. We are forwarding Permit No. SW8 110415
dated May 5, 2011, for the construction of the subject project.
This permit shall be effective from the date of issuance until May 5, 2021, and shall be subject to the
conditions and limitations as specified therein. Please pay special attention to the Operation and
Maintenance requirements in this permit. Failure to establish an adequate system for operation and
maintenance of the stormwater management system will result in future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right
to request an adjudicatory hearing upon written request within thirty (30) days following receipt of this
permit. This request must be in the form of a written petition, conforming to Chapter 150B of the
North Carolina General Statutes, and filed with the Office of Administrative Hearings, P.O. Drawer

binding.
If you have any questions, or need additional information concerning this matter, please contact Chris
Baker, or me at [phone].

Wet Detention Basin Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record11 be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected,repaired or replaced immediately. These deficiencies can affect the integrity
of structures,safety of the public,and the removal efficiency of the BMP.

This system (check one):
❑ does ® does not incorporate pretreatment other than a forebay.
Important maintenance procedures:
— Immediately after the wet detention basin is established,the plants on the
vegetated shelf and perimeter of the basin should be watered twice weekly if
needed,until the plants become established(commonly six weeks).
— No portion of the wet detention pond should be fertilized after the first
fertilization that is required to establish the plants on the vege 44EtefEIVED

— If the basin must be drained for an emergency or to perform I -. ance,the
flushing of sediment through the emergency drain should be a - • a e
maximum extent practical.
— Once a year,a dam safety expert should inspect the embankment.
After the wet detention pond is established,it should be inspected once a month and
within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a
Coastal County). Records of operation and maintenance should be kept in a known set
location and must be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

Attention: Mr. Lee Galloway

Reference: Seasonal High Watertable Estimate
Proposed Stormwater Pond MAY 0 2 2011
Intercontinental Hardwoods BY.
Pender County,North Carolina
RFTS Job No. 631-11
Dear Mr. Galloway:
RFTS is pleased to provide testing services during the design phase of stormwater system for the
Intercontinental Hardwoods addition located off Porters Road in Pender County,North Carolina.
Specific site grading plans had not been provided to us at the time this report was prepared.
DESCRIPTION OF ACTIVITIES AND FINDINGS
As requested, our staff visited the site on April 7, 2011, to estimate the seasonal high watertable
and classify the soils at one location near the center of the proposed pond. The purpose of this
testing was to provide soil parameters for stormwater design.
Seasonal High Watertable Estimate
A hand auger boring was advanced at one location near the center of the proposed pond to a
depth of approximately 4 %2 feet below the existing ground surface near the center of the
proposed stormwater pond. The encountered soils were logged and visually classified by depth
and a Munsell Soil Color Chart was used to determine the hue, value,and chroma of the visually
distinct soil layers. Our soil logs are presented in Table 1.
Soils encountered in our boring consisted of fine to medium sand with Silt (USCS Soil Group
SM) in the upper 40 inches below the ground surface. From 40 inches to 50 inches fine to
medium sand with clay (USCS Soil Group SC) was encountered. Below 50 inches and
continuing through the boring termination depth of 52 inches sandy Clay was encountered.
Comparison of the soils to the Munsell Chart and observations made while on site suggests the
presence of a zone of aerated soils indicative of the seasonal water level approximately 13 inches
below the ground surface within the unsaturated zone. Measurements made 30 minutes after
augering indicate a depth to standing water in the borehole of 13 inches below the existing
ground surface.

Stormwater Drainage System & Erosion Control RECEIVED
Narrative MAY 0 2 2011
Inter-Continental Hardwoods BY.
6841 Malpass Corner Road, Currie,NC
The Inter-Continental Hardwoods project is an existing lumber facility located at 6841
Malpass Corner Road in Pender County (Parcel ID # 2276-79-6116-0000) and is owned
by DLH Nordisk, Inc. The site is approximately 37.6 acres and contains existing
infrastructure such as roads, buildings, drainage structures, and water and sewer systems.
DLH Nordisk, Inc. is proposing to construct three new buildings that total 31,000 sf,
roads, future impervious and a forebay and wet detention pond system. The total
impervious area for this project is 724,773 sf, all of which will be treated in the proposed
detention basin.
The site will have one drainage area consisting of 1,638,925 sf(37.62 ac). No off-site
runoff flows onto the site and therefore, none will be routed to the proposed BMP. All
outflow from the drainage basin will drain to Lee Ditch; classification C;Sw, Index No.
18-68-18-11-1-1, in the Cape Fear River Basin. All built up areas (BUAs) will be
collected and routed to a wet detention pond BMP.
The drainage area will be treated by one wet detention pond sized to collect the first 1.5"
of runoff storm and 90% TSS removal. The wet detention pond was designed to meet or
exceed current State and County requirements and is designed for high density projects.
The pond will be sized to hold the required pre/post development volume difference for a
24-hr. 1-yr., 2-yr., 10-yr. and 25-yr. storm events. The pond has also been designed to
include a 20-foot emergency spillway to handle flow from a 100-yr. storm event.
Outflow from the wet detention pond will be to a proposed 24" HDPE drainage pipe that
will drain off-site. The SHGWT elevation is approximately 13" below the existing
ground elevation.
Prior to clearing of the site, one construction entrance and temporary silt fence will be
installed. After clearing of the project site, the detention pond will be constructed to
include the proposed forebay, wet detention pond, and the temporary skimmer. The
proposed road areas and building locations will then be graded. Underground utilities,
including the stormwater drainage system will be installed and inlet protection put into

TE 11004
place. The proposed buildings will be constructed followed by paving, final site grading,
and stabilization of the site. Temporary erosion control measures will remain in-place
until such time as when areas are stabilized. Permanent measures include permanent
stands of grass and energy dissipaters. Specific measures and directions to the contractor
are noted on the plans. Please refer to Sheet C3 for detail erosion control measures and
construction sequence.
Summary
For this 37.6 ac. drainage area, all on-site drainage will be collected by a stormwater
drainage system and routed to a forebay and wet detention pond. The pond has been
sized to retain the pre/post development runoff for the 24-hour 1-yr, 2-yr, 10-yr. and 25-
yr. storm events and to capture the first 1.5" of runoff from the new development. The
pond outlet structure was designed to release the required first 1.5" runoff volume over 2
days to 5 days as well as control the release of the various year storms to the off-site
drainage point. A 20-foot emergency spillway was added to the pond in order handle the
drainage from a 100-yr. storm event. Temporary erosion control measures include one
gravel construction entrance, silt fence, inlet protection and skimmer. Permanent erosion
control measures include energy dissipaters and established grass areas.
